The specification of the Ultrasonic meter has been already standardized in the city gas industry, and sharing the main parts for the LPG meters. The specifications of U-BUS and U-BUS Air have been already standardized by NPO Japan Utility Telemetering Association (JUTA) at the end of FY 2010. PHY and MAC Layers for U-Bus Air were proposed to IEEE 802.15.4 g/e, and they have been adopted as standards at the end of FY 2011.
